TL;DR: It is shown that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians; and early European farmers, who were mainly of Near Eastern origin but also harboured west Europeanhunter-gatherer related ancestry.

TL;DR: It is suggested that Y-STR loci are useful markers to identify males and male lineages in forensic practice and recommended for the forensic application of a basic set of 7 STRs for standard Y-haplotyping in forensic and paternity casework.

TL;DR: It is shown that the initial peopling followed a southward expansion facilitated by the coast, with sequential population splits and little gene flow after divergence, especially in South America.

TL;DR: The chromosome Y STRs seem to be very useful in comparing closely related populations which cannot probably be separated by e.g. autosomal STRs, but in order to be used in an evolutionary context they need to be combined with more stable Y-polymorphisms e.
